Cooler air is on the way this weekend.
WASHINGTON — It’s feeling like May with highs near 70 degrees Friday, but winter may have one last run before it’s all said and done.
A cold front gives us cooler air this weekend, as temperatures will dip to the 50s this weekend.
By Monday, highs will fall to the 50s with some p.m. clouds.
Before you break out the snow boots again, let’s talk about the likelihood of snow on Monday in the DMV. On a scale of 1 to 5, with 5 being the highest chance of this happening, we are looking at a “1” — it’s not impossible, but there are several hurdles to this becoming reality.
- It may be too warm for snow. Throughout the day on Monday, highs and lows will be above freezing, which is not conducive for accumulating snow. The GFS Model is running cold enough in the upper levels of the atmosphere Monday to produce snow and now the European model is also forecasting some wet snow in the DMV Monday.
- The track and timing is not a lock. The European model guidance doesn’t bring in the precipitation until Monday night. The GFS starts off Monday earlier with some colder air in place.
The European is dry Monday morning.
By Monday night the European model has snow over most of the DMV.
At best, in the immediate D.C. area under the colder solution, the snow falls but accumulates only on grassy surfaces.
It’s not uncommon to get snow in March even after spring in the DMV. Recently we’ve had snow in D.C. in March in 2018 and 2017. We average 1.6″ of snow at National and 2.9″ at Dulles for the month of March.
